VoIP Configuration Example
This chapter describes an example of the AT-2716POE adapter
supporting both data and VoIP Ethernet traffic.
VoIP Support
The AT-2716 POE is a two port adapter with a 100FX fiber port and a
100TX copper port capable of supporting a Class 3 PoE device. This
unique port configuration allows a PoE device to be attached to a
standard desktop workstation on the copper port and communicate down-
stream through the a secured 100FX fiber link. The PoE device could be
a VoIP phone, a WiFi Access Point, or a security camera that requires
between 0W to 15.4W of PoE power.
In networks where the primary connection for your computer workstation
is a fiber backbone, the fiber port on your AT-2716 POE adapter can be
configured to separate the data for your computer workstation from the
data on the copper port connected to a PoE device such as VoIP (Voice
over IP) phone. This application is accomplished by installing Allied
Telesis’s ATMux configuration utility which allows bridging
between the ports and the configuration of Virtual Local Area Networks
(VLANs) for the ports.
A VLAN is a group of ports on an Ethernet LAN that form a logical
Ethernet segment. These ports form an independent traffic domain where
the traffic generated by the nodes of a VLAN remains within the VLAN. In
this case, you can create a separate VLAN for the data from your
computer and a second VLAN for the data from VoIP PoE phone. The
incoming and outgoing Ethernet traffic is tagged accordingly for the
computer and the VoIP phone. This tagging can be done either by the
phone, or in cases where the phone does not support VLAN tagging, by
the ATMux Configuration Utility.
